WISI DB 53 D SAT End Socket Flush-Mount 3-Output (SAT/TV/Radio) 5-862 & 950-2150 MHz 75 Ohm

For satellite distribution in residential and commercial buildings, the WISI DB 53 D provides a reliable single connection point for SAT, TV, and radio signals. Its flush-mount design integrates seamlessly into standard wall boxes, making it ideal for living rooms, offices, and hotel installations where a clean finish is essential.

Key specifications

• Socket type: SAT end socket (Stichdose) with three outputs: SAT (F-connector female), TV (IEC male), and radio (IEC female).
• Frequency range: 5–862 MHz for TV/radio and 950–2150 MHz for SAT, covering all common terrestrial and satellite bands.
• Low insertion loss: 1.5 dB on both TV/radio and SAT paths, ensuring minimal signal degradation.
• DC pass on SAT output: supports up to 500 mA for powering LNBs or multiswitches.
• High shielding effectiveness: >85 dB (Class A) to prevent interference and maintain signal integrity.
• Return loss: >10 dB across all bands for excellent impedance matching.
• Impedance: 75 Ohm, standard for coaxial distribution systems.
• Mounting type: flush-mount (Unterputz) for a neat, professional appearance.
• Housing material: die-cast zinc for durability and long-term reliability.

Why choose it

This socket combines robust construction with precise RF performance. The die-cast zinc housing shields against external noise, while the DC pass feature simplifies powering satellite equipment without extra cables. Its three dedicated outputs eliminate the need for separate wall plates, saving space and installation time.

Ideal use cases

• Connecting a satellite receiver, TV, and FM radio in a single room.
• Multi-dwelling units where each apartment requires individual SAT/TV/radio outlets.
• Upgrading existing antenna sockets to support modern satellite and terrestrial signals.

Good to know

The socket is designed for standard 75-ohm coaxial cabling. Professional installation is recommended to achieve optimal signal quality. The F-connector output is compatible with common screw-on or push-on connectors.
